| Abstract: | The Ultra-Violet Imaging Telescope (UVIT) on board AstroSat is unique in its capability for high-resolution ultraviolet imaging (<1.5") and low-resolution (λ/δλ ≈ 100) slitless spectroscopy, offering a wide field of view of ∼0.5 degrees. Now nearly a decade in operation, UVIT remains a key resource, producing data of immense value to the scientific community. We will present an overview of the latest version (7.0.1) of the UVIT pipeline and introduce "Arivu", a newly defined high-level version of UVIT data products. All high-level products generated using pipeline versions with a major version number of seven are now collectively termed "Arivu." This updated pipeline version includes two significant improvements over the previous version (6.3): (a) a higher level of success in combining episode-wise images, and b) a higher level of success and smaller residual errors in the astrometric fit. We will discuss the specific solutions that made these advances possible. The Arivu version of the science-ready UVIT data has been available at the Indian Space Science Data Center of the Indian Space Research Organisation since 01 June 2024. |
